Caller ID Block overview
Using either your phone’s keypad or the Vonage Business Communications User Portal, you can block caller ID on any of your outbound calls. Those you call will see “Unavailable” or “Blocked” rather than your business name and phone number.
How to use Caller ID Block
It’s easy to block caller ID for our outbound calls: within the Admin Portal, simply choose the extension you’d like blocked, select that setting and save. Want to set it for your entire account? You can do that too, also within the Admin Portal.
